feat(bar): Barbarian Class Final Quality Gate & E2E Verification (30/30 Skills)

- Complete E2E verification across all 30 Barbarian skills (IDs 126–155)
- Cross-tree Warcry buff duration network (Shout, Battle Orders, Battle Command)
- Berserk 100% magic conversion & zero-defense vulnerability duration
- Frenzy momentum speed scaling & dual-wield requirements
- Whirlwind uninterruptible path sweeping & 4-frame hit checks
- War Cry 5-band physical damage progression & stun length
- Combat Masteries & Critical Strike sequential roll without 4x stacking
- Refined weapon matching for cryptic axe, poleaxe, and mauls
- Enforces BATCH1_SKILLS length invariant = strictly 38
- Fixes #467
